Trim looks a bit high there to have the engine running, I know it says you can upto around 1000 revs but I wouldn't recommend it. It could seriously shorten the life of the universal joint.
Glad you got it sorted Carl. I suspect you were either in shallow water or forgot the leg was up, I have to agree with Gaz, if it can be avoided all the better.
I'm just sitting here thinking, it's a real shame you didn't manage to get a high speed pass shot, or better still high speed turn for a header picture.
Really shallow water just barely 3ft... had just let the missus off so she could get some video (was a waste of time as the video didn't come out properly) ..
not going to get any chance this year now ... unless by some magical reason the sun might come out to play for a few hours or so while the tide is sensible ....
